Title: Improvements in motor vehicle suspensions having shock absorbing or damping means
IPC: B60G17/015
Filed: 1936-01-06
Abstract: 473,121. Controlling shock-absorbers. GODSAL, C. P. L. Jan. 6, 1936, No. 459. [Class 108 (iii)] A resilient suspension for a motor vehicle includes at least one pair of double-acting, non-resilient, hydraulic shock-absorbers each having inertia-actuated means comprising an eccentrically-pivoted weight controlling a liquidrestricting valve, and stop means for limiting the movement of the weight so disposed that the weight can only leave its neutral position to restrict the flow of liquid in response to centrifugal force directed outwards relatively to the longitudinal axis of the vehicle. As shown in Figs. 2, 4 the shock-absorber comprises a double-vane 15 integral with the operating spindle 12 and co-operating with partitions 17 projecting inside the casing 10 to force liquid from chambers 18a, 18d to chambers 18b, 18c respectively, and viceversa, through pairs of ducts 19a, 19b and 19c, 19d and slots 22, 22x in a valve spindle 21 rotatably mounted in a transverse passage 20. A centrifugally-acting eccentric weight 23 is secured to one end of the spindle 21 and enclosed in a housing 24 integral with the casing 10, the weight normally being pressed against an adjustable screw-stop 27 on one side of the housing by a bow-spring 26. The same shock-absorber may be used on the right or left-hand side of the' vehicle as required by the provision of an alternative threaded boss for the screw 27. In order to dispense with packing for the valve spindle 21 the housing 24 is made oil-tight and connected with the casing 10 by a passage 30 controlled by a non-return valve 31. In a modification, the screw-stop 27 is replaced by a slidable stop connected by a push-and-pull member with a dashboard control. Fig. 6 shows another construction in which the controlling valve of a standard shock-absorber, mounted coaxially and rotatably in the spindle, has a projecting end 35 provided with an arm 36 engaging a fork 37 mounted on a spindle 38 rotatably supported in brackets 39 secured to the operating arm 11. A further arm 40 fixed to the spindle 38 carries the inertia weight 41 which, when swung outwardly by centrifugal force, rotates the spindle 38 which moves the fork 37 to rotate the valve member 35. The weight is maintained in its inoperative position by spring means 26‹ which pulls the fork against an adjustable stop 27‹. According to the Provisional Specification, in order to prevent excessive pressures in the shock-absorbers, the control valve may be arranged not to close completely or a small auxiliary leak may be incorporated in the valve or may byepass the valve. It is also stated that the resistance of the shockabsorbers may be further regulated by the driver.

Title: Improvements in or relating to mowing or like machines
IPC: A01D34/06
Filed: 1921-01-05
Abstract: 178,512. Kontio, T., (Tehdasosa-keyhtio Takomo). Jan. 5, 1921. Mowing-machines.-A mowing-machine provided with means for adjusting the height of the cutters has means operated by a radial movement of the cutter-carrying frame to render the drive to the cutters inoperative after the cutters have been raised a determined height above the ground. The cutter bar 23 engages at its end in a tube 22 carried by a frame 18, 19 mounted on a sleeve 13 on the axle 10 of the road wheels 11, 12. The near side member 19 is clipped loosely on the sleeve and the other member 18 is provided with an elongated hole 21 through which the sleeve 13 parses. The reciprocation of the cutters is effected by a lever 26 pivoted on the cutter frame and rocked by a stud 30 engaging in the groove 31 of a rotary cam 32 carried by a stud shaft mounted on the cutter frame and driven by a gear 33 engaging a gear wheel 36 on the main axle. The cutter bar is provided with lifting-gear operated by a treadle lever 37 and a hand-lever 38. The treadle lever carries a shoulder engaging a quadrant 40 pivoted on the draught frame 14 and connected by a link 41 to the cutter frame. The other end of the quadrant is connected by a link 42 to a, spring 43 attached to the frame 14, this spring tending to lift the cutters. The handlever 38 is provided with a link 44 which is also pivoted to the quadrant 40. In operation the cutters are first lifted by depressing the treadlelever and then the lifting operation is completed by pulling over the hand-lever. To disconnect the cutter drive on raising the frame, a cam-slot- 47 formed in a member 46 secured to the tube 13 is engaged by a stud 48 carried by the frame member 18. As the cutters approach their highest position the stud 48 and the frame member 18 are forced outwards by the cam, thus freeing the pinion 33 from its engagement with the gearwheel 36. As a further means of adjustment of the cutters the cutter bar may be rocked in the tube 22 by an arm 51 connected by a link 50 to a lever 49 with a rack-quadrant 52. Shoes 55, 54 may be provided at the inner and the outer ends of the cutters respectively, and the shoe 54 may carry a bracket 56 to which a cleaning board 57 may be loosely connected. The forward end of the cutter frame may be attached to the frame 14 by a link 60 and chain 61 so that the frame may be adjusted to suit the height of the draught animal. Reference has been directed by the Comptroller to Specifications 8662/02, 4700/09, 22028/09, 12728/10 and 140,886.

Title: Apparatus and method for efficiently coupling digital signals to a communications medium in information packets
Inventor: PRICE JOHN DAVIS
IPC: H04L29/06
Filed: 1996-05-02
Abstract: An improved Packet Assembler/Disassembler (PAD) (200) optimizes the assembling of characters into packets for transmission over a packet network (150). The PAD is arranged to operably connect to and receive character asynchronous data from one or more terminal instruments (600) operating in either a block transfer mode or an echoplexing mode. Characters received by the PAD from a terminal instrument operating in an echoplexing mode are forwarded with no PAD delay. Characters received by the PAD from a terminal instrument operating in a block transfer mode are similarly forwarded with no PAD delay and in full packets with the exception of the last few characters of each block of characters which only partially fill their respective packets. And these partially filled packets are quickly forwarded in a time period which just exceeds the period required for the reception of a single character at the rate of data reception from the terminal instrument.
